Summary: You can use graphics in personal or commercial projects, you cannot use the graphics as the primary integrity of your product, you must provide attribution (svgbackgrounds.com/attribution)
And before anyone rips off my head, attribution can be placed inside commented out code, so it doesn't need to take away from your design.
Edit: upon further investigation, access isn't something that's just thrown around willy nilly! It usually goes for $120/yr!
